Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, specifically is related to a novel adjustable beam clamp for building construction. BACKGROUND

[0002] In modern construction engineering, frame structures are widely adopted due to their excellent load-bearing capacity and flexible spatial layout. However, beam formwork reinforcement in frame structures often faces the following problems in traditional construction processes.

[0003] During the formwork reinforcement stage, if the reinforcement measures are not in place, it is easy to cause insufficient stability of the formwork system during concrete pouring operations. This will result in concrete seeping out of the formwork joints, i.e., the phenomenon of concrete leakage, which in turn causes honeycomb and pitted defects on the surface of the concrete formation. In more serious cases, it may even result in serious quality problems such as holes and exposed steel bars. During the construction process, due to inaccurate installation and positioning of the formwork or uneven external forces acting on the formwork during concrete pouring, the axis position of the beam formwork may shift, and the elevation may also deviate. After the concrete is poured and the formwork is removed, it is easy to detect that there is a deviation between the actual position of the beam and the axis position designed for the building. In addition, due to insufficient strength and stiffness of the formwork or uneven stress under the action of concrete lateral pressure, the beam formwork structure may deform. When the formwork is removed, it can be found that the concrete beam exhibits abnormal deformation such as bulging, necking, or warping, which will adversely affect the structural performance and appearance quality of the beam.

[0005] However, the above structure has a fixed distance between the multiple clamping grooves, which makes it inconvenient to adjust the position of the clamping block according to the specific size requirements of different specifications of beam formwork. For example, when the width of the beam formwork does not match the spacing of the clamping grooves, the clamping block is difficult to accurately position to the ideal clamping position, which may cause problems such as loose contact between the clamping block and the beam formwork or excessive clamping damage to the formwork. Moreover, the fixed spacing of the clamping grooves limits the adaptability of the clamp to various building structural scenarios. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0024] In order to further understand the features, technical means and specific purposes and functions achieved by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0025] Referring to Figures 1-3 As shown in the figure, a novel adjustable beam clamp for building construction, comprising a reinforcing assembly 1 for reinforcing the beam formwork, the reinforcing assembly 1 comprising a reinforcing steel plate 11 and a galvanized square steel tube 12 slidingly arranged in the reinforcing steel plate 11 and extending outwardly from the reinforcing steel plate 11, a clamping block 13 arranged on the reinforcing steel plate 11 and the galvanized square steel tube 12 respectively and used for clamping the beam formwork and in the shape of a T-shaped groove, and a screw rod 14 arranged on the reinforcing steel plate 11 and used for driving the galvanized square steel tube 12 to slide in a horizontal and linear direction, the adjustable beam clamp further comprising a positioning assembly 2 arranged on the reinforcing steel plate 11 and used for locking the rotating screw rod 14.

[0026] When the beam formwork at the construction site needs to be clamped on both sides, first rotate the screw rod 14, and then drive the galvanized square steel tube 12 to slide outwardly along the gap-fitted reinforcing steel plate 11 when the screw rod 14 is rotating, and thus the clamping block 13 arranged on the galvanized square steel tube 12 can be moved synchronously. The clamping force and the load transmission when clamping the beam formwork can be effectively dispersed, and the clamping distance of the clamping block 13 can be fine-tuned by arranging the positioning assembly 2, so as to ensure that the beam formwork does not deform during the pouring of concrete. And it can adapt to beam formworks of different sizes and shapes, ensuring the safety of construction personnel.

[0027] Referring to Figures 1-3 As shown in the figure, the reinforcing assembly 1 further comprises a gasket 15, a nut 16, a positioning plate 17 and a side plate 18; the gasket 15 is arranged on the screw rod 14 and located in the reinforcing steel plate 11, and a through hole is formed in the gasket 15 for the screw rod 14 to pass through; the nut 16 is arranged on the screw rod 14 and close to one side of the gasket 15; the positioning plate 17 is arranged on the reinforcing steel plate 11, and a through slot is formed in the positioning plate 17 for the screw rod 14 to pass through; and the side plate 18 is arranged on the galvanized square steel tube 12 and threadedly connected with the screw rod 14.

[0028] The side plate 18 is welded to the galvanized square steel tube 12, and the side plate 18 is threadedly connected with the screw rod 14, so that the screw rod 14 can drive the galvanized square steel tube 12 to stably slide in the reinforcing steel plate 11 when rotating. When installing the screw rod 14, first weld the gasket 15 and the nut 16 to the screw rod 14, and then weld the positioning plate 17 to the reinforcing steel plate 11, so that the screw rod 14 can be quickly assembled with the reinforcing steel plate 11, simplifying the installation steps and facilitating the workers to assemble on site.

[0029] Referring to Figure 5As shown, the positioning assembly 2 comprises a ratchet tooth 21, a positioning column 22, a rotating tab 23, a mounting plate 24 and an extension spring 25; the ratchet tooth 21 is arranged on the screw rod 14 and close to one side of the positioning plate 17; the positioning column 22 is arranged on the positioning plate 17 and above the ratchet tooth 21, and the positioning column 22 is in a cylindrical shape; the rotating tab 23 is rotationally arranged on the positioning column 22 and on one side of the ratchet tooth 21; the mounting plate 24 is arranged on the positioning plate 17 and below the rotating tab 23; the extension spring 25 is arranged on the mounting plate 24 and on one side of the rotating tab 23, one end of the extension spring 25 is fixedly connected with the mounting plate 24, and the other end of the extension spring 25 is fixedly connected with the rotating tab 23; when the ratchet tooth 21 rotates, the rotating tab 23 is in an intermittent meshing state with the ratchet tooth 21 under the pushing force of the extension spring 25.

[0030] When the screw rod 14 rotates, the ratchet tooth 21 will rotate synchronously. In the rotating process of the ratchet tooth 21, the rotating tab 23 in contact with the ratchet tooth 21 will swing along the positioning column 22, and in this process, the rotating swing of the rotating tab 23 will cause the extension spring 25 to be compressed. During the rotation of the screw rod 14, the rotating tab 23 will not form a clamping state with the ratchet tooth 21. When the screw rod 14 rotates and completes the clamping operation of the beam formwork by the clamping block 13, the rotating tab 23 will always be clamped with the ratchet tooth 21 under the elastic pushing of the extension spring 25. In this way, it can effectively prevent the screw rod 14 from rotating due to the outward pushing force of the clamping block 13 during the pouring process of the beam formwork, ensuring the clamping effect of the clamping block 13 on the beam formwork and avoiding the self-rotation of the screw rod 14.

[0031] Referring to Figure 5 As shown, the positioning assembly 2 further comprises a mounting block 26, a rotating rod 27 and a plug rod 28; the mounting block 26 has a pair of and is arranged on the rotating tab 23 respectively; the rotating rod 27 is rotationally arranged on the mounting block 26 and above the rotating tab 23; the plug rod 28 is threadedly arranged on the rotating rod 27 and close to one side of the positioning plate 17; the reinforcing steel plate 11 is provided with a plug hole 29 matched with the plug rod 28.

[0032] When the rotating rod 27 rotates, it can drive the rotating rod 27 and the plug rod 28 to rotate synchronously, and in this state, the plug rod 28 does not rotate and is inserted into the plug hole 29. After the screw rod 14 stops rotating and the clamping block 13 clamps the beam formwork, the rotating rod 27 is in a clamping state with the ratchet tooth 21, and when it is necessary to release the clamping state, the rotating rod 27 is first pulled towards the extension spring 25, thereby driving the rotating rod 27 to rotate along the positioning column 22, at this time, the rotating rod 27 can be separated from the ratchet tooth 21 and the clamping state is released, and in this state, the plug rod 28 corresponds to the position of the plug hole 29, and then the plug rod 28 is rotated into the plug hole 29, so that the worker can smoothly rotate the screw rod 14 in the reverse direction.

[0033] Referring to Figures 4-6 As shown in the figure, the adjustable beam clamp further comprises a sliding assembly 3 arranged on the galvanized square steel pipe 12, the sliding assembly 3 comprising sliding balls 31 and a setting plate 32; the galvanized square steel pipe 12 is provided with a plurality of ball grooves 121 extending along the extension direction of the galvanized square steel pipe 12; the sliding balls 31 are provided in the ball grooves 121 respectively; the galvanized square steel pipe 12 is provided with a mounting groove 122 in the shape of a cuboid; and the setting plate 32 is mounted on one end of the galvanized square steel pipe 12.

[0034] During the sliding of the galvanized square steel pipe 12 inside the reinforcing steel plate 11, the sliding balls 31 slide in the ball grooves 121. When the galvanized square steel pipe 12 slides, the sliding balls 31 are in contact with the reinforcing steel plate 11 and slide smoothly, effectively improving the smoothness and stability of the sliding of the galvanized square steel pipe 12 and reducing the friction resistance and jamming phenomenon.

[0035] Referring to Figure 6 As shown in the figure, the setting plate 32 is provided with a plurality of circular grooves 321 extending along the extension direction of the galvanized square steel pipe 12, and the diameter of the circular grooves 321 is smaller than the diameter of the sliding balls 31. When the sliding balls 31 are placed in the circular grooves 321, the sliding balls 31 are in abutting contact with the circular grooves 321.

[0036] The galvanized square steel pipe 12 is provided with a plurality of threaded holes, and the setting plate 32 is provided with a plurality of butt joints corresponding to the positions of the threaded holes. The butt joints are provided with bolts for quickly mounting the setting plate 32 into the mounting groove 122 provided on the galvanized square steel pipe 12. When mounting the setting plate 32, the sliding balls 31 are placed in the circular grooves 321 of the setting plate 32 in sequence, and then the setting plate 32 is placed in the mounting groove 122 of the galvanized square steel pipe 12. At this time, the sliding balls 31 are in abutting contact with the circular grooves 321 and the ball grooves 121 respectively, thereby realizing the quick mounting and dismounting of the sliding balls 31.

[0037] The working principle is as follows: firstly, the gasket 15 and the nut 16 are welded on the screw rod 14, and then the positioning plate 17 is welded on the reinforcing steel plate 11, so that the screw rod 14 and the reinforcing steel plate 11 are quickly assembled. The side plate 18 and the galvanized square steel pipe 12 are installed by welding, and the side plate 18 and the screw rod 14 are connected by threads. When the screw rod 14 rotates, the galvanized square steel pipe 12 can stably slide in the reinforcing steel plate 11, so that the clamping block 13 arranged on the galvanized square steel pipe 12 moves synchronously. The structure can effectively disperse the clamping force when the beam formwork is clamped and transmit the load, and can also finely adjust the clamping distance of the clamping block 13, so that the beam formwork does not deform during the concrete pouring process, and can adapt to beam formworks of different sizes and shapes, and ensure the safety of construction personnel. When the screw rod 14 rotates, the ratchet teeth 21 rotate synchronously. During the rotation of the ratchet teeth 21, the rotating push piece 23 in contact with the ratchet teeth 21 rotates and swings along the positioning column 22, so that the extension spring 25 is compressed. During the rotation of the screw rod 14, the rotating push piece 23 does not form a clamping state with the ratchet teeth 21. After the rotation of the screw rod 14 is completed and the clamping operation of the beam formwork by the clamping block 13 is completed, the rotating push piece 23 is always clamped with the ratchet teeth 21 under the elastic force of the extension spring 25. In this way, the rotation of the screw rod 14 caused by the outward thrust of the clamping block 13 during the pouring of the beam formwork can be effectively prevented, the clamping effect of the clamping block 13 on the beam formwork is ensured, and the self-rotation of the screw rod 14 is avoided. When the rotating push rod 27 rotates, the push rod 27 and the insertion rod 28 rotate synchronously, and at this time the insertion rod 28 does not rotate and is inserted into the insertion hole 29. After the screw rod 14 stops rotating and the clamping block 13 clamps the beam formwork, the rotating push rod 27 is in a clamping state of the ratchet teeth 21. If the clamping state is to be released, first pull the push rod 27 towards the extension spring 25, drive the rotating push rod 27 to rotate along the positioning column 22, so that the rotating push rod 27 is separated from the clamping of the ratchet teeth 21, at this time the insertion rod 28 corresponds to the position of the insertion hole 29, then rotate the insertion rod 28 into the insertion hole 29, so that the worker can reversely rotate the screw rod 14 smoothly. During the sliding of the galvanized square steel pipe 12 in the reinforcing steel plate 11, the sliding ball 31 slides in the ball groove 121. When the galvanized square steel pipe 12 slides, the sliding ball 31 contacts and smoothly slides with the reinforcing steel plate 11, effectively improving the smoothness and stability of the sliding of the galvanized square steel pipe 12, reducing the friction resistance and jamming phenomenon. The galvanized square steel pipe 12 is provided with a plurality of threaded holes, the setting plate 32 is provided with a plurality of butt joints corresponding to the positions of the threaded holes, and the butt joints are provided with bolts for quickly installing the setting plate 32 into the mounting groove 122 of the galvanized square steel pipe 12. When the setting plate 32 is installed, the plurality of sliding balls 31 are sequentially placed in the circular groove 321 of the setting plate 32, and then the setting plate 32 is placed in the mounting groove 122 of the galvanized square steel pipe 12, so that the sliding balls 31 are respectively abutted in the circular groove 321 and the ball groove 121, thereby realizing the quick installation and disassembly of the sliding balls 31.

It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application.
